Solar cells more efficient thanks to new material standing on edge
Researchers from Lund University and from Fudan University in China have successfully designed a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material’s ability to self-organise by standing on edge. One of the researchers behind the discovery is Tönu Pullerits, from the Division of Chemical Physics.
The study was recently published in the journal Advanced Energy Materials.
Cholesterol - a key player at the lung surface
Cholesterol, a naturally occurring compound at the lung surface, has been shown to have a clear effect on the properties of this nanoscale film that covers the inside of our lungs. Cholesterol levels in this system may affect the lung’s function, according to researchers at Lund University who have published a new study on the significance of cholesterol for lung surface properties. One of the researchers behind the discovery is Emma Sparr, from the Division of Physical Chemistry. The new findings provide new insights into this vital physiological system. Read more

Silver atom nanoclusters could become efficient biosensors
Donatas Zigmantas and his colleague Erling Thyrhaug (both from the Division of Chemical Physics), together with researchers from the University of Copenhagen have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging.
In a new study they have studied nanoclusters consisting of 20 silver atoms. For the first time, the researchers managed to measure the exact energy levels and identified that the ultrafast energy flow is linked to the structural changes that occur when light excites these nanoclusters. The process is indescribably fast. It happens in less than one millionth of a millionth of a second. The study was recently published in Nature Communications. Read more

KILU DAY 2017 – Save the date!
This year´s department day, The KILU day 2017 will be October 12th.
Lund University Student and Staff party & pre-party – 15 September
On Friday, 15 September 2017, there will be a 350th anniversary celebration for all employees and all students at Lund University. It has not been decided when the main event begins, but a guess is that it starts at approximately 18.
Before the main event there will be pre-party, one for each faculty. For students and employees at LTH as well as at the three departments that belong both to LTH and to the Faculty of Science, there will be a joint pre-party on the LTH campus, in the form of a picnic around Lake Sjön (if weather permits). All employees at the Department of Chemistry are welcome to the joint pre-party. The pre-party will start at 14:00.
Sign-up-form for the pre-party:
The sign up form is for current employees and current students (spring 2017). Deadline is June 16.
For students starting in the autumn of 2017 and for new employees after June 16, there will be a chance to sign up later (deadline probably at the end of August).

Ventilation restrictions this summer on the ventilation in building 1 at Kemicentrum
The landlord Akademiska hus will during the summer perform a repair on the ventilation system in building 1 (the fan motors must be replaced). When the work is in progress the ventilation capacity will be limited, which means that it is not possible to work with an open hatch on all fume hoods. Use as few fume hoods as possible. Pull down the hatch on the fume hood if you hear a local alarm from the fume hood.
The work to replace the fan motors in building 1 begins on Monday 19/6 in the eastern part in accordance with the following timetable.
Stage 1: June 19-July 30 (fan 1, east part of building 1)
Stage 2: 7 August-1 September (fan 1 and 2, west part of building 1)
Stage 3: 1 September-15 September (fan 2, east part of building 1)
At Lund University

Last but not least...
100 years since the birth of Stig Sunner
Stig Sunner, born on May 13, 1917, was the primary driving force in the creation of Kemicentrum at Lund University.
His doctoral research was conducted in the Department of Organic Chemistry leading to a thesis (1949) on thermodynamic properties of some organic sulphur compounds. His work included the design of a novel type of combustion calorimeter, which for the first time allowed accurate determination of enthalpies of formation of organic sulphur and halogen compounds - data important in theoretical and industrial chemistry.
Sunner’s thesis attracted the attention of thermochemists in USA, and in 1952 he was invited as a visiting scholar for some months to the thermodynamic laboratory of the US Bureau of Mines in Bartlesville, OK, which at that time was a leading laboratory in the development of calorimetric methods. He was much impressed by the open atmosphere at that laboratory and found the scientists much more communicative on scientific matters compared to his experiences from Lund. During his stay in USA, Sunner also visited some larger research institutes, like MIT, Caltech and UC Berkeley. The research environment he encountered in the US made a lasting impression, which came to influence his views about the organization and management of scientific institutions.
Sunner’s visit in Bartlesville brought him in contact with several scientific organizations, especially the International Union of Pure and Applied Chemistry (IUPAC) and the North American Calorimetry Conference (now called Calcon), which later would lead him into extensive engagements with international scientific projects, in particular regarding standards, nomenclature and compilation of thermodynamic data. Sunner became President of IUPAC’s Physical Chemistry Division (1971-1973) and he received Calcon’s highest honour, the Huffman Award. As a recognition of Sunner’s achievements in thermochemistry, Calcon in 1980 founded the Stig Sunner Award, an annual prize given to young scientists in thermodynamics or thermochemistry.
During the time period 1949 – 1956, Sunner had a position as “docent” in the Department of Organic Chemistry at Lund University. His working conditions then became very poor, especially in relation to his scientific skill and enthusiasm. His situation was noticed by NFR and TFR (now the Swedish Research Council) leading to the formation of a separate research position for him, together with a grant that made it possible to form “The Thermochemical Laboratory” at the Chemistry Department. In 1977, Sunner was appointed Professor of Thermochemistry.
In the early 1960s, Sunner formed a vision for a future Center for chemical research and education at Lund University, in which all chemistry institutions at Lund University would form a Center with a joint management of the different departments. Furthermore, important service functions, like workshops, should be shared by all departments of the Center. His ideas were based on his own experiences at the Department of Chemistry and on impressions gained from his many contacts with national and international chemical research institutions.
In order to implement a Chemical Center he carried out an intense lobbying campaign, locally as well as nationally. Kemicentrum was formally established in 1967 and was located in a complex of new buildings that formed one of the largest chemical research institutes in Europe.
Sunner had a failing health in the 1970s, probably partly due to his exceptionally high working pace. He died of a heart attack, Kemicentrum, on June 3, 1980.
